The Acquainted is the One who places everything in its correct position.

(… وَهُوَ الْقَاهِرُ فَوْقَ عِبَادِهِ) (And He is the subjugator over His servants.…): Meaning, He (swt) does not leave matters up to cause and effect. However, He has arranged the universe and creation via causes and effects and made connections and mediums between one thing and another. For example, the earth is the connection or medium for the growing of plants and the human being is the connection or medium between his father and his son. He has put links between these causes and effects, but He is the Irresistibly Powerful over His slaves. Thus, He can break these causes and effects whenever and wherever He wills, to announce the liberty of His Divine Power, in situations which can be observed by human beings in the various parts of their lives. For example, a person might fall from a high place and not get injured, while another person might just trip over his prayer mat, fall and die. For another person, the doctors might say that there is no hope of him recovering, but he recovers. Therefore, the breaking of the laws of the universe happen time and again, so that human beings will know that Allah (swt) is the Irresistibly Powerful over His slaves.
